Do you have a spare disk with at least the same size than your problem
disk? Then do a byte-by-byte backup first, to prevent even more damage
during the following experiments. At least backup the MBR with
dd if=/dev/hda of=backup.mbr count=1 bs=512
if you use some Linux bootdisk
dd if=/dev/ad1 of=backup.mbr count=1 bs=512
if you use FreeBSD
First you must know, how your partition table looks like at the moment.
A good tool to check this, is Linux fdisk from some bootable floppy
(tomsrtbt) or CD (Knoppix), but any other free DOS tool is as good.
If you don't write changed data back to disk, there is no danger to do
- If there is a valid partition table still on disk, you're lucky.
If I understand you correct, then you had a working Win XP before?
Then I would first try to boot from the XP CD and start the recovery
console from there. On the command line appearing there, you can enter
"fixmbr" and "fixboot". I don't know exactly how this will deal with
corrupt partition tables, however.
- If there is no partition table left on disk, things are more
difficult. Do you know how (which tool, which size) you partititioned
your disk in the first place? If yes, then you always have the chance to
exactly reproduce your disk layout and regain your data by doing the
same steps again.
